Black Forest Labs releases FLUX 3 Image with layout controls

Black Forest Labs has published FLUX 3 Image, presenting native 2K and 4K generation with more controlled editing. The model page highlights pixel-level control and a workflow that uses bounding boxes to target a region before changing it. It also supports image references for jobs that must preserve or combine visual details.

For product teams, the shift is from asking for a whole new image to making a bounded change inside an existing composition. That fits catalog cleanup, interface mockups, and storyboards where layout matters. It gives a clear test: did the target change while the rest stayed stable?

Try fixed source images with one edit per bounding box. Score placement, identity preservation, unwanted changes outside the target, and output size. Keep human approval until the model is reliable on your real assets.
